Abstract
The invention discloses am Imipramine Hydrochloride drop pill prepared through ultramicro disintegration and drop pills manufacturing technique, which has the advantages of improving collapse and dissolving speed, quick effect, increased medicament stability, reduced adjuvant consumption, lowered production costs, and easiness in carrying and use. It has good compliance, thus is especially suitable for children, the elderly, bedridden patients and dysphagia patients.
Description
Technical field
The present invention relates to a kind of pharmaceutical product and preparation method thereof, specifically meclozine hydrochloride drop pill and preparation method thereof.
Background technology
Meclozine hydrochloride is a histamine receptor antagonists, the pressure reduction effect that can cause antihistamine, and the animal dead that the lethal dose histamine is caused shields, and has maincenter to suppress and local anesthetic action, its anti-motion sickness is relevant with its cholinolytic effect with stun effect.
Meclozine hydrochloride onset in oral back 1 hour, t
1/2Be 6 hours, medication once can be kept 8～24 hours.List marketing at present the meclozine hydrochloride sheet only arranged, clinical be used for that motion sickness causes feel sick, vomiting, dizzy treatment and prevention.To vestibular disease cause dizzy also effective.
Meclozine hydrochloride is tasteless, little smelly, soluble,very slightly in water, its disintegration of tablet time is longer, absorption difference, and bioavailability is low, the supplementary product consumption ratio is big, child, old people, bed patient and dysphagia patients are taken inconvenience, and compliance is poor, have influenced the performance of meclozine hydrochloride therapeutical effect.
The present invention makes the meclozine hydrochloride drop pill by using ultramicro communication technique and dropping pill formulation Technology exactly, thereby overcomes the above defective of meclozine hydrochloride sheet, and the therapeutical effect of meclozine hydrochloride is given full play to.
Summary of the invention
The meclozine hydrochloride drop pill of making by using ultramicro communication technique and dropping pill formulation Technology not only have disintegrate molten loose fast, steady quality, the pill volume is little, and is easy to carry and use, and onset is rapid, compliance is good, be particularly suitable for the characteristics that child, old people, bed patient and dysphagia patients are taken, but also have working condition and production equipment is simple, production cost is low, compare the advantage that supplementary product consumption reduces with tablet, demonstrated fully the new drug research exploitation spirit that people-oriented.
For achieving the above object, the present invention by the following technical solutions: the meclozine hydrochloride fine powder of 1 weight portion through micronizing is added in 1～10 weight portion molten matrix, fully mixing, dropping preparation method is condensed into ball in coolant, remove coolant, drying, promptly.
The chemical name of meclozine hydrochloride is the 1-[(4-chlorphenyl among the present invention) benzyl]-the 4-[(3-tolyl) methyl]-piperazine dihydrochloride, molecular formula is C
25H
27ClN
22HCl, molecular weight are that 463.88 structural formulas are
Substrate among the present invention includes but not limited to polyethylene glycol 6000, Macrogol 4000, polyethylene glycol 1500, cetomacrogol 1000, sodium stearate, glycerin gelatine, poloxamer, stearic acid, glycerol monostearate acid, insect wax etc.
Coolant among the present invention includes but not limited to dimethicone, liquid paraffin, vegetable oil, water, alcoholic solution etc.
Below through detecting to beneficial effect of the present invention as directed
One, detects index and method
